Laboratory Activity 4.2- 4.3 Danielle Robinson Exercise Physiology Lab 1-28-13 Laboratory Activity 4.2 1. Name | Height | Weight | HR (heart rate) | BP (blood pressure) | Stephanie Diminquez | 64 in. | 104 lbs | 92 | 102/80 | Stage | Time (min) | Workload (kg) | HR (beats * min) | BP (mmHg) | RPE | 1 | | 96 | | 130/80 | 15 | 2 | 6 | 96 | | 135/80 | 17 | 3 | 9 | 152 | | 135/80 | 18 | 4 | 12 | 112 | | 125/80 | 18 | 2. Systolic blood pressure increases, while the diastolic blood pressure maintains the same or slightly decreases as the intensity of exercise and activity increases. The larger number usually characterizes the systolic blood pressure which precedes the diastolic. 3. The left main artery stenosis, moderate stenotic valvular heart disease, known electrolyte abnormalities, high-degree atrioventricular block, mental of physical impairment leading to inability to exercise adequately, sever arterial hypertension, chronic infection, uncontrolled metabolic disease, and tachyarrthymias or bradyarrythmias are all relative contraindications relating to blood pressure during an exercise test. Laboratory Activity 4.3 Name | Height | Weight | HR (heart rate) | BP (blood pressure) | Jonathan Gerardo | 172.5 cm | 190 lbs | 88 b/min | 130/80 | 1. | Time | Workload (kg) | HR (beats*min) | BP (mmHg) | RPE | Resting | | 0 | 88 | 130/80 | 6 | Handgrip | 1 | 9 | 84 | 130/90 | 7 | Wall sit | 1 | n/a | 122 | 180/100 | 15 | 2. Isometric exercise did not significantly affect the systolic and diastolic blood pressure. A greater amount of force or energy exerted is needed to cause a substantial change. 3. The response of blood pressure varies between arm exercises compared to leg exercises. Reason being, a 30% MVC in kg is required for arm exercises while a 50% MVC is measured during leg exercises.
